Solve -3/8r=1/4

$$- \frac { 3 } { 8 } r = \frac { 1 } { 4 }$$

Solve for r

$$r=-\frac{2}{3}\approx -0.666666667$$

Steps for Solving Linear Equation

Multiply both sides by -\frac{8}{3}, the reciprocal of -\frac{3}{8}.

$$r=\frac{1}{4}\left(-\frac{8}{3}\right)$$

Multiply \frac{1}{4} times -\frac{8}{3} by multiplying numerator times numerator and denominator times denominator.

$$r=\frac{1\left(-8\right)}{4\times 3}$$

Do the multiplications in the fraction \frac{1\left(-8\right)}{4\times 3}.

$$r=\frac{-8}{12}$$

Reduce the fraction \frac{-8}{12} to lowest terms by extracting and canceling out 4.

$$r=-\frac{2}{3}$$
